A cyberattack disrupted the sale of heavily subsidised gasoline in Iran on Tuesday, state media reported, causing long queues at gas stations across the country weeks before the anniversary of 2019 street protests that followed fuel price hikes.

Iran says it is on high alert for online assaults, which it has blamed in the past on its arch-foes United States and Israel. The United States and other Western powers meanwhile have accused Iran of trying to disrupt and break into their networks.

"The disruption at the refuelling system of gas stations ... in the past few hours, was caused by a cyberattack," state broadcaster IRIB said. "Technical experts are fixing the problem and soon the refuelling process...will return to normal."
